How it compares
Drawn to scale against the 13.1 cm average and a few objects you can picture.
What this size means
Clearly above average, and still inside what clinicians actually measure: roughly 1 in 400 men are longer. Bigger is not automatically what partners pick. In a study using 3D-printed models, women chose about 16 cm long and 12.2 cm around for a long-term partner (Prause et al., 2015).
